Fast Decision Snapshot for Procurement Teams
The QR50 is most relevant when a project needs a fixed access reader that can accept QR credentials while also supporting an RFID card technology selected through the correct model variant. A buyer should not choose only by the QR50 family name because the BE/WE versions are intended for 125kHz ID cards while the BM/WM versions are intended for 13.56MHz IC cards. Communication choice also matters: Wiegand and ZK RS485 serve different integration needs, and ZKTeco guidance specifically distinguishes RS485 for certain dynamic-code workflows and Wiegand for static-code use with particular controller scenarios.
Controlled doors and visitor entry points where QR and card credentials need to coexist.

Product Overview
The ZKTeco QR50 QR Code Reader is designed for access-control environments where organizations want to present more than one type of credential at the point of entry. Traditional proximity or smart-card systems remain common in offices, residential communities, hotels, education sites and managed facilities, but many projects now also need QR credentials for visitors, temporary users, mobile workflows, event-style entry or applications where issuing a physical card to every person is unnecessary. The QR50 addresses that transition by combining code recognition with RFID reading in a compact 86 × 86 × 50 mm format.
The reader recognizes QR as well as Data Matrix, PDF417, EAN13, EAN8, UPC-A, UPC-E0, UPC-E1, Code128, Code 39, Code 93 and CodaBar. For practical scanning, ZKTeco specifies 360-degree rotation and a ±45-degree tilt identification angle, which gives users flexibility in how a code is presented. The stated reading distance is at least 5 cm for codes and at least 4 cm for cards. These values should be treated as the vendor’s operating reference rather than a promise for every phone screen, printed code, ambient-light condition or card construction, because real deployment quality can still depend on credential presentation and installation conditions.
A major selection point is the variant. QR50BE and QR50WE support 125kHz ID cards, with black and white color options respectively. QR50BM and QR50WM support 13.56MHz IC cards, again in black and white. This distinction matters to businesses replacing an existing card reader: the same physical-looking reader family can be incompatible with the organization’s current cards if the wrong frequency is ordered. Buyers should therefore identify existing card technology before comparing quotations.
For UAE projects, FourTeck.com can help procurement teams translate the application requirement into a more accurate reader request. Useful information includes the access controller model, whether QR codes are static or dynamic, the existing card type, expected number of doors, color preference, power source, cabling plan and any software workflow that generates credentials. This allows the quotation discussion to focus on compatibility and project fit rather than only model name and unit cost.
Key Business Benefits
◆ QR and Card Access in One Reader
A business can support QR-based entry without automatically abandoning card credentials. This is useful when permanent employees still use cards while visitors, contractors or temporary users receive QR credentials through a compatible access-control workflow.
◆ Flexible Controller Integration
Wiegand and ZK RS485 communication give system designers more than one integration path. The correct interface depends on controller capability and credential workflow, so this flexibility helps projects align the reader with an existing or planned access-control architecture.
◆ Broad Code Recognition
Support for QR, Data Matrix, PDF417 and multiple 1D barcode formats makes the reader useful for projects where credential generation may not be limited to a single symbol type. Buyers should still confirm which code format their application actually outputs.
◆ Choice of RFID Technology
The family offers separate variants for 125kHz ID cards and 13.56MHz IC cards. This lets buyers choose according to the credential technology already deployed rather than forcing a migration simply to introduce QR reading.
◆ Compact Deployment Footprint
At 86 × 86 × 50 mm, the device can fit many wall-mounted reader positions without requiring a large terminal. A compact reader is especially helpful where the access controller and decision logic are located elsewhere in the system.
◆ Better Procurement Planning
Because the QR50 family clearly separates card technology by variant, procurement teams can standardize a reader choice once they have confirmed controller interface and credentials. That can reduce the risk of ordering visually similar but technically unsuitable units.
Product Highlights That Matter in a Real Access-Control Project
A product highlight is only useful when it changes a buying decision. For the QR50, the important points are not decorative features; they determine whether the reader can recognize the credential, communicate with the controller and fit the planned installation.
The supported code list includes QR, Data Matrix, PDF417 and several retail-style 1D formats. This broad recognition can simplify integration where credential systems produce different visual code types, but the controller and software still need to interpret the received data correctly.
The vendor specifies 360° rotation with ±45° tilt. Users do not need to hold a printed or screen-based code in one exact rotational orientation, which can improve convenience at busy entry points.
Choose QR50BE or QR50WE for 125kHz ID cards, or QR50BM or QR50WM for 13.56MHz IC cards. This must be confirmed before purchase because it is a hardware variant choice, not a setting that can be switched after installation.
The reader supports standard Wiegand protocol and ZK RS485. ZKTeco’s own support guidance indicates that interface choice can matter for static versus dynamic QR workflows with specific controllers, so this point should be discussed during system design.
The specified operating temperature is -20°C to 60°C, with 20% to 80% operating humidity under the vendor’s stated reference condition. Buyers should still confirm enclosure and environmental suitability for the actual installation location.
Before ordering, confirm whether the project needs black or white, 125kHz or 13.56MHz, Wiegand or RS485, and whether the QR credential is static or dynamically generated. These four questions normally reveal more about fit than a generic request for a QR reader.

The specification table gives the verified hardware reference, but choosing a correct configuration requires context. For example, an office using legacy 125kHz proximity cards should not automatically order a 13.56MHz IC-card version just because it is available at a similar price. Likewise, a visitor-management workflow that generates dynamic QR codes may need a different communication approach from a basic static QR pass. ZKTeco’s support material for InBio460 Pro specifically points to RS485 for dynamic QR codes and Wiegand for static codes in that scenario. That guidance should be matched to the exact controller and software environment rather than applied blindly to every installation.
Buyers should also distinguish between reader capability and complete access-control functionality. The QR50 presents credential data to a compatible controller; door locking, permissions, schedules, event logging, remote management and software behavior depend on the wider access-control platform. FourTeck.com can help review these dependencies so procurement teams request the reader together with any controller, lock, power, exit device, cabling or software components required by the project.
Configuration and Buyer Guidance
An access-control reader purchase becomes much easier when the buyer separates credential questions from controller questions. Start with the credential. Will permanent users present a 125kHz ID card, a 13.56MHz IC card, a QR code, or a combination? If cards are already in circulation, identify their technology rather than assuming every RFID card is compatible. Then confirm how QR codes will be created and whether they are static for repeated use or dynamic for time-sensitive or changing access workflows.
Share the controller model and available reader inputs. This determines whether Wiegand or ZK RS485 is the more appropriate integration path.
Choose BE/WE for 125kHz ID cards or BM/WM for 13.56MHz IC cards. Confirm existing credentials before ordering.
Describe how codes are generated, how long they remain valid and which software/controller workflow processes them.
Check locks, power supply, exit button, door sensor, controller capacity, cable path, mounting point and any software licensing separately.
For a multi-door rollout, buyers should also think about standardization. Decide whether all sites use the same card technology and reader color, whether every door needs QR entry, and whether the controller estate is consistent. Mixed controller generations can create integration differences that are easy to miss in a unit-price comparison. If you are replacing another reader, provide a photo or model number of the existing device, the controller model and wiring interface. If the project is new, provide the number of controlled doors, preferred credential type, expected visitor process and any physical installation constraints. FourTeck.com can use those details to structure a more relevant quotation and identify compatible related components.
Ideal Business Use Cases
The QR50 is best understood as a credential-reading component inside a wider access-control system. Its value is strongest in environments where businesses want fast presentation of QR credentials while retaining card access for selected users.
Office Visitor Entry
Reception teams can use QR-based visitor credentials with a compatible controller and visitor-management process while employees continue using cards. This can reduce the need to issue temporary physical cards for every short visit.
Residential or Community Access
Managed residential environments may combine resident cards with QR access for approved guests, service personnel or temporary entries. Final suitability depends on the controller, credential rules and property access policy.
Hotel and Hospitality Areas
Hospitality projects may use QR credentials for controlled spaces or temporary access where a compatible system supports the workflow. The 125kHz versus 13.56MHz choice should be aligned with any card credentials already used on site.
Managed Retail or Unattended Areas
The reader can support controlled entry in unmanned or limited-staff environments when combined with an access controller and business application that validates the presented credential. Reader capability alone does not provide payment, identity or authorization logic.
Contractor and Temporary Workforce Access
Project sites and managed facilities can consider QR credentials for temporary personnel where access permissions change more frequently than permanent employee badges. Dynamic or time-sensitive operation must be planned with the supporting controller and software.
Card-System Modernization
Organizations with an established Wiegand or RS485 access-control estate may use the QR50 family when adding QR reading at selected doors. Compatibility should be verified door by door if the installed controller base is mixed.
In each use case, the important boundary is the same: a reader recognizes and passes credential information, while the access-control platform determines whether the credential is accepted, what door action occurs, and how the event is recorded. Buyers should therefore evaluate the QR50 alongside controller capacity, software capabilities, lock hardware, network architecture and operational policy. FourTeck.com can help identify which of these project inputs should be confirmed before quotation.
QR50 Multi-Format Credential Reading
Many access-control projects begin with a simple phrase such as “we need QR entry,” but that phrase leaves several technical questions unanswered. The QR50’s strength is that it is not limited to a single visual code format. In addition to QR, it can recognize Data Matrix, PDF417 and multiple 1D codes including EAN, UPC, Code128, Code 39, Code 93 and CodaBar. This gives integrators and business application teams more flexibility when credentials originate from different systems. However, code recognition should not be confused with application-level acceptance. The reader still needs to send data in a form that the connected controller and software understand.
The specified 360-degree rotation and ±45-degree tilt can improve presentation convenience. At a reception barrier or door, users may show a phone at slightly different angles or present a printed pass without carefully rotating it. This tolerance can make the reader easier to use, especially for visitors who have not been trained on a specific access device. The stated code reading distance of at least 5 cm provides a useful deployment reference, although phone brightness, print quality, reflections, screen protectors, code size and ambient conditions can influence real-world presentation.
For procurement teams, the business question is whether multiple code formats and convenient presentation reduce friction in the intended workflow. If the project will only ever issue one controlled QR format, broad code recognition may be a secondary advantage. If the site expects credentials from several systems or visitor sources, it becomes more important. Before purchase, confirm the exact code format, whether credentials are static or dynamic, how validity is checked, and which component makes the access decision.
QR50 Controller Integration and Communication
A reader that recognizes the right credential is only half of an access-control design. The second half is getting credential data to the controller reliably and in the format expected by the system. The QR50 provides Wiegand, RS485 and USB communication. ZKTeco identifies standard Wiegand protocol and ZK RS485 protocol as the primary operating interfaces, while its regional documentation notes USB for firmware-update use. For most door-access projects, buyers should therefore focus on whether the existing or planned controller supports the required Wiegand or RS485 connection.
Interface choice can also be related to the credential workflow. ZKTeco’s support guidance for using QR50 with an InBio460 Pro indicates RS485 for dynamic QR codes and Wiegand for static codes in that specific deployment context. That is useful evidence that “QR support” is not a single universal integration mode. A buyer planning time-varying visitor credentials should share the controller and software details rather than assuming that a static QR proof of concept guarantees dynamic-code compatibility.
Wiegand remains widely used in access-control systems because it can integrate many reader and controller combinations, while RS485 offers a different communication architecture used by compatible ZKTeco systems. Neither should be selected simply because one appears newer. The correct choice depends on controller input, cable design, system logic and software requirements. If replacing an existing reader, identify the current wiring and controller port before removing equipment. If designing a new site, plan communication method together with door power, lock power, exit device, door sensor and controller capacity.
FourTeck.com can help turn these design inputs into a practical quotation checklist. For a single door, the information may be minimal. For a building with many doors, consistent communication design can reduce commissioning effort and future maintenance complexity. Procurement teams should ask the project engineer or installer to confirm interface requirements before finalizing the reader variant.
QR50 Deployment Flexibility and Variant Planning
The QR50 family uses a simple variant structure, but that simplicity can still cause ordering mistakes if the suffix is ignored. BE and WE are 125kHz ID-card versions, while BM and WM are 13.56MHz IC-card versions. The second letter also separates black from white models: the black options are BE and BM, while WE and WM are white. For a single door this may feel like a small detail; in a standardized office or hospitality rollout, a wrong suffix can create a card-compatibility or visual-consistency problem across many locations.
Variant planning should begin with the installed credential population. If a business already has thousands of cards in circulation, preserving that technology may be more practical than changing card type just to add QR access. On the other hand, a new project can evaluate 125kHz and 13.56MHz options in the broader context of security policy and the rest of the access-control platform. The QR50 itself does not convert one card technology into another, so the hardware choice must match the intended credentials from the beginning.
Physical deployment also deserves attention. The reader measures 86 × 86 × 50 mm and operates from DC 12V (±5%) or USB 5V according to vendor specifications. Its stated operating range is -20°C to 60°C and 20% to 80% humidity under the published reference condition. These figures do not automatically establish an ingress-protection rating or suitability for exposed outdoor installation, so buyers should not infer weatherproofing unless it is specifically confirmed for the exact product and site condition.
A good quotation request should therefore include more than “QR50, quantity 20.” Specify the suffix if known, card technology, black or white preference, controller interface, indoor or protected installation conditions, and whether the readers are part of a replacement or new-build project. That information helps FourTeck.com identify the correct supply request and reduces avoidable clarification later.
What Should You Know Before Choosing This Reader?
Business buyers often know the outcome they want—faster visitor entry, mobile QR credentials, compatibility with existing cards or a cleaner multi-door rollout—but not which reader variant or interface is required. The questions below help technical and non-technical stakeholders turn that requirement into a more accurate purchasing brief.
Is this reader suitable for an office visitor-management project?
Yes, when the visitor platform and access controller can generate, receive and validate the intended QR credentials. The reader can recognize QR codes and pass data through supported interfaces, while permanent employees can still use the appropriate RFID card variant. Confirm how visitors receive codes, whether they are static or dynamic, and which controller makes the door-access decision.
Which QR50 variant should I choose if my company already uses proximity cards?
First identify the card frequency. QR50BE and QR50WE support 125kHz ID cards, while QR50BM and QR50WM support 13.56MHz IC cards. Do not select by color or price alone. If the existing card technology is unclear, confirm it from the current reader, card specification or access-control administrator before requesting the final quotation.
Can I use dynamic QR codes with the reader?
Dynamic QR workflows can be supported in compatible ZKTeco scenarios, but they require the right controller and communication method. ZKTeco’s own support guidance for InBio460 Pro directs dynamic QR operation through RS485 and static QR through Wiegand. Because the exact workflow depends on controller and software, share both product names before assuming compatibility.
Will it work with any controller that has a Wiegand input?
ZKTeco positions the reader for connection to controllers that support Wiegand input, but a successful project still depends on data format, controller settings and the QR application. Basic card reading may be straightforward, while advanced or dynamic QR behavior can require additional compatibility checks. Confirm the exact controller model and expected credential flow before deployment.
What should I check when replacing an older card-only reader?
Check card frequency, controller input, wiring, reader power, physical mounting space and the current door hardware. The new reader can add QR capability, but it should not disrupt the credentials already used by employees. If the old system uses 125kHz cards, ordering a 13.56MHz model would create an avoidable migration problem.
Do I need extra software or licenses just to scan QR codes?
The reader recognizes supported codes, but the wider system must decide what those codes mean and whether access is permitted. Software, licenses or subscriptions depend on the selected controller and credential platform, not on the reader specification alone. Ask your system provider which component creates the QR credential and validates its permissions.
Can one project mix QR access and RFID card access?
Yes, that is one of the practical reasons to consider this reader family. A compatible deployment can allow some users to present QR codes and others to use RFID cards. The chosen hardware variant determines the card technology, while controller and software rules determine which users or credentials are authorized at each door.
What should be planned for a multi-door rollout?
Standardize the reader suffix, card technology, communication interface and color wherever possible. Also check controller port capacity, power, cable routes, locks and software configuration for every door group. If different buildings use different controller generations, document those differences before ordering so the same reader assumption is not applied to incompatible infrastructure.
What information gives FourTeck.com enough detail for an accurate quote?
Provide quantity, controller model, 125kHz or 13.56MHz card requirement, black or white preference, static or dynamic QR use, project location and whether the reader is replacing an existing unit. If you also need locks, controllers, power supplies or exit devices, list those items so the quotation can reflect the wider door requirement.
Business Requirements to Match Before You Buy
For businesses that need visitor QR access
Use the reader with a compatible controller and visitor workflow that can issue and validate the required codes. Decide whether the credential is static or dynamic before selecting the communication method.
For organizations keeping existing cards
Match the reader variant to the installed card frequency. The family supports either 125kHz ID cards or 13.56MHz IC cards depending on model, so card compatibility should be confirmed before quote approval.
For multi-door standardization
A consistent suffix, interface and color can simplify procurement and maintenance across many doors. Mixed controller estates should be mapped first because the same communication choice may not fit every installed panel.
For card-reader replacement projects
Check the old reader’s wiring, voltage, card frequency and controller connection. The goal should be to add the required QR capability without unintentionally making existing employee cards unusable.
For projects that need compatible accessories
Plan controllers, electric locks, power supplies, exit buttons, door sensors, cabling and software separately. The QR reader is a credential component, not a complete door-control package.
For procurement teams comparing quotations
Compare quotations only after the card technology and exact suffix are aligned. Two quotes for different QR50 variants may look comparable but serve different installed credential environments.
What Buyers Should Check Before Purchase
A correct access-reader purchase requires more than confirming the model family. The first check is variant accuracy. Determine whether the project needs a black or white reader and whether the RFID credential is 125kHz ID or 13.56MHz IC. The second check is controller compatibility. Confirm that the connected panel accepts the intended Wiegand or ZK RS485 communication and that the software workflow can process the data coming from the reader.
Configuration Fit
Specify QR50BE, QR50WE, QR50BM or QR50WM when possible. If the suffix is unknown, state card frequency and color preference so the correct version can be identified.
Compatibility Check
Share the controller make and model, reader input type and software platform. QR recognition alone does not guarantee that every controller can implement the desired access logic.
Availability and Warranty
Ask for current variant availability and the warranty terms attached to the actual quoted supply. Do not assume all colors, frequencies or quantities have the same lead time or coverage.
Quote Preparation
Provide door count, reader quantity, controller model, card technology, QR type, project location, required accessories and installation status. This reduces back-and-forth during commercial review.
Buyers replacing an older device should also check physical fit, cable route and power. The QR50 dimensions are published, but the existing wall box or mounting arrangement may differ. If the reader is intended for an exposed or harsh environment, ask specifically about enclosure suitability rather than inferring weather resistance from temperature data. No ingress-protection claim should be assumed unless it is confirmed for the exact model being supplied.
Long-term cost planning should include the surrounding system. Reader price is only one element; controllers, locks, power supplies, software licensing, visitor-management functions, installation labor and future credential issuance may be more significant in a multi-door project. For bulk supply, confirm whether all doors need QR capability or whether only visitor entrances, reception points and selected zones require it. FourTeck.com can help review a bill of quantities and identify where the reader fits within the wider access-control requirement.
UAE Availability and Service Support
FourTeck.com supports business inquiries for access-control readers and related components across Dubai and the UAE. For the QR50 family, availability can vary according to the required suffix, color, card technology, supplier status, project quantity and timing. Because the BE/WE and BM/WM variants are technically different, it is useful to confirm the exact requirement before treating any availability statement as suitable for your project.
Quote support can include a review of card frequency, controller model, QR credential type, communication interface and quantity. If a project also requires access controllers, electric locks, exit buttons, door sensors, power supplies or related infrastructure, these can be discussed as part of the same purchasing requirement. FourTeck.com can coordinate delivery requirements based on the confirmed order and business location, while final timing depends on product availability and logistics at the time of quotation.
Warranty guidance should also be confirmed against the actual quoted source and supply terms. Different supply channels or project agreements can have different coverage, so buyers should request written warranty information rather than relying on a generic assumption. For organizations preparing a tender or bill of quantities, sharing the requested model suffix and door schedule can make the commercial response more precise.
Business Coverage Across Key UAE Locations
Organizations in Dubai, Abu Dhabi, Sharjah, Ajman and other UAE locations can contact FourTeck.com for reader availability guidance, configuration review and quotation assistance. The practical requirement may differ by site: a head office could need employee cards plus visitor QR entry, a residential project may need controlled guest access, and a hospitality environment may have different card technology or controller standards. FourTeck.com can help buyers structure the model request around those operational differences.
For project supply, provide the destination, number of readers, exact or preferred QR50 suffix, controller model and any required accessories. Delivery coordination and lead time are confirmed during the quotation process and can vary by variant, quantity and supplier status.
Regional Supply Enquiries for GCC and Africa
FourTeck.com also receives business technology enquiries from selected GCC and Africa markets where organizations may be standardizing access-control hardware across more than one country. Projects in Saudi Arabia, Qatar, Oman, Kuwait and Bahrain can have different delivery, customs, warranty and installation requirements from UAE projects, even when the reader model is the same. Buyers should therefore treat regional supply as a project-specific discussion rather than assuming one delivery method or commercial term applies everywhere.
For Africa-region requirements, including Kenya and Uganda, project teams can share the required quantity, access controller model, card technology and deployment schedule so sourcing options can be reviewed. Regional availability, shipping arrangements and warranty handling depend on country, supplier status and order structure. Large multi-site projects may benefit from a standardized hardware schedule that identifies reader suffix, color, controller interface and accessory requirements for each location.
Useful FourTeck regional channels include FourTeck Kenya, FourTeck Uganda, FourTeck Africa and FourTeck Kuwait. These links can be used for regional enquiries while the Dubai-based FourTeck.com site remains the main point for UAE purchasing assistance.
Other ZKTeco Options and Related Access-Control Components
A buyer may decide that QR50 is the correct reader, or may discover during design that a different reader family, control panel or supporting component fits the project better. The goal is to compare by credential workflow, controller compatibility, environment and door architecture rather than by model name alone.
ZKTeco QR500 Series Reader
Consider for projects evaluating another ZKTeco QR and RFID reader family. Compare supported card technology, environmental requirements, controller interface and physical format before substitution.
ZKTeco QR600 Series Reader
A suitable comparison when a project needs to evaluate a different QR-reader form factor or environmental specification. Final fit should be checked against the exact QR600 variant.
ZKTeco Access Control Panels
The reader requires a compatible controller to make door-access decisions. Panel choice should consider door count, reader interfaces, software compatibility and the required credential workflow.
ZKTeco Brand Solutions
For a standardized project, it can be helpful to review readers, panels and related ZKTeco components together so communication and software requirements are considered as one system.
Door Hardware and Accessories
Electric locks, exit buttons, door sensors, power supplies and cabling may be required in addition to the reader. The exact bill of quantities depends on the door design and controller.
Alternative selection should be based on verified compatibility rather than assuming a newer or larger model is automatically better. FourTeck.com can help compare related reader families when the project brief includes card technology, QR workflow, controller model and installation environment.
Why Business Buyers Contact FourTeck.com
Access-control procurement often looks simple at the line-item stage and becomes complicated during installation. A reader can have the right brand and still be wrong for the card technology, controller interface or QR workflow. FourTeck.com approaches the request as a configuration and sourcing problem rather than treating every model code as interchangeable.

Frequently Asked Questions
What is the ZKTeco QR50 QR Code Reader used for?
It is an access-control reader that can recognize QR and several other barcode formats while also reading RFID cards according to the selected variant. It connects to a compatible access controller through supported interfaces. Typical projects include visitor entry, community access, hospitality, managed facilities and locations where QR credentials need to work alongside physical cards.
What is the difference between QR50BE, QR50WE, QR50BM and QR50WM?
The key differences are card technology and color. QR50BE is black and QR50WE is white; both use 125kHz ID cards. QR50BM is black and QR50WM is white; both use 13.56MHz IC cards. Buyers should confirm both the existing credential technology and preferred finish before choosing a suffix.
Which code formats can the reader recognize?
The vendor lists QR, Data Matrix, PDF417, EAN13, EAN8, UPC-A, UPC-E0, UPC-E1, Code128, Code 39, Code 93 and CodaBar. Recognition of a code does not automatically mean the access-control software will accept it as a valid credential; the controller and application still need the correct configuration.
Does the QR50 support Wiegand and RS485?
Yes. ZKTeco specifies standard Wiegand protocol and ZK RS485 protocol, with communication listed as Wiegand, RS485 and USB. The correct interface depends on the controller and credential workflow. For some dynamic QR scenarios, ZKTeco support guidance directs users to RS485, so the exact application should be checked before installation.
How far away should a QR code or card be presented?
ZKTeco states a code reading distance of at least 5 cm and a card reading distance of at least 4 cm. These are product reference values. Real-world presentation can be influenced by code size, phone screen, print quality, card construction and installation conditions, so commissioning tests should be performed at the actual door.
Can FourTeck.com help choose the correct model?
Yes. Share your controller model, card frequency, preferred black or white reader, static or dynamic QR requirement, quantity and installation context. FourTeck.com can use those details to help clarify which variant should be quoted and whether related controllers, locks, power supplies or other door components should be included.
Is the reader available for UAE projects?
FourTeck.com can support UAE availability enquiries, but current supply depends on the exact suffix, color, card technology, quantity and supplier status at the time of request. Availability should therefore be confirmed during quotation rather than assumed from the model family alone. Project delivery requirements can be reviewed after the correct variant is identified.
What warranty applies to the product?
Warranty terms should be confirmed with the actual FourTeck.com quotation because coverage can depend on sourcing channel and supply terms. Buyers preparing a formal project purchase should request the applicable warranty information in writing and include any special support or replacement requirements in the procurement brief.
Can businesses request bulk supply for multiple doors or sites?
Yes, project and bulk enquiries can be prepared around the required quantity and site structure. For a multi-door or multi-site rollout, provide a door schedule, controller types, card technology, reader color and accessory requirements. Standardizing these details helps avoid mixed variants and gives purchasing teams a clearer basis for comparing the final quotation.
